Elsa spent hours in her family archive every day. As Queen, her advisors said she should know every major detail concerning the kingdom's past. She had already finished all of the books in the archive. She knew every detail about Arendelle's past; exports, imports, wars, famines. Anything. She had even added her own scroll telling the story of the eternal winter she accidently caused.

She looked out the window and eyed the North Mountain. She loved that she didn't have to hide anything from the Kingdom anymore but she yearned for adventure. The freedom she experienced outside her castle sparked her desire for that type of life; a life with no responsibilities or expectations. She snapped out of her thoughts and returned her attention to the bookshelves and thought, I can't think like this anymore. I am the Queen.

She walked along each of the shelves, brushing her hand against the books until she reached an empty space. There was only one book missing from the archive – her parent's. Luckily the Royal Advisors were able to band together and write a short novel on the major events that happened in the past few years. Elsa stared at the blank space for a few more seconds when a sudden knocking brought her back to reality. She spun around and thought to herself, I really need to stop day dreaming.

The knocks were uneven and came in a set of five. Recognition flashed across Elsa's face as she realised who was at the door. Anna. Her sister was the only person Elsa really felt comfortable around. "Come in Sis!"

Anna opened the door and ran to give Elsa a hug. As usual she had a huge smile across her face. Elsa could see Anna was excited about something. She wondered what it could be. Maybe Kristoff finally asked Anna for her hand in marriage. Elsa couldn't keep her curiosity at bay any longer. "What's made you so crazy Anna?"

"Elsa, you'll never believe it! The guards were cleaning out Mom and Dad's room and they found all this cool stuff! There's so many trinkets from all these different kingdoms that I didn't even know about!" She reached into her bag and pulled out a small ruby. When she held it up to the light Elsa noticed how perfect it was. Never had she seen such a flawless gem before.

"Wow, that's amazing Anna! As soon as I finish up in here I'll be sure to stop by your room and take a look at everything," Elsa said, as she noticed a flash of disappointment on Anna's face. It was there for barely a second, but she noticed it.

"When do you think you'll be finished?"

She could leave whenever she wanted to but there was something about looking through her parent's things that didn't appeal to her. She lied and said, "I still have a few books to finish, I'll try to finish them as fast as I can though."

"Oh…okay." Anna looked down at the floor as she said, "It just feels like I'm losing you again. I don't want to go back to the way things were." She looked towards the door. "I just can't go back to knocking on a door that would never open."

Elsa noticed Anna's eyes starting to glisten. She was crying. Elsa quickly went back to her sister and hugged her as tight as she could. She had no idea what to say but she whispered, "I will never leave you alone like that again. I promise."

Anna wiped her face dry and the smile returned to her face. "Thanks Elsa, that means a lot to me. Well I better go get ready, Kristoff wants to take me out by the lake tonight. He thinks he's romantic or something."

Elsa couldn't help but laugh. Anna always made fun of Kristoff for his romantic escapades, but Elsa knew she secretly loved them. "Dinner by the lake with the city lights illuminating the mountains in the background? Yeah definitely doesn't sound romantic to me Sis. Have fun!"

Anna smirked and started heading for the door. As she reached the exit she spun around and said, "I almost forgot! The guards found this book hidden under a panel in Dad's drawer. I haven't looked at it yet, I thought you would want to see it first. You should read it when you get the chance." Anna grabbed the book out of her bag and tossed it to Elsa. "I never liked reading anyways. Okay I need to run, I'm late. Bye!" She ran out of the room, leaving Elsa speechless.

Elsa looked at the cover of the book. There was no title, just the royal symbol. Just like the rest of the archive books. Could this really be the missing piece? She opened the book and recognized her Father's handwriting scribbled across the pages. She was too excited to read anything, she just kept flipping pages until she recognized her name. She read:

One of our longest allies, the Kingdom of Corona, has suffered a great loss today. The Queen's child has gone missing. She fears her second child, the twin sister of the first, may suffer the same fate so she has sent her to live here until they can find the missing princess. The Queen of Corona was only expecting one child, so the Kingdom assumes that their only child has gone missing. They wish to keep it this way to protect their remaining child. We have promised to raise her as our own until it is safe for her to return home. No one will know of Elsa's origin until the day it is safe for her to return home.

Elsa dropped the book and sat down. She could feel the room spinning around her. She was so confused and scared. What did this mean? She looked down and noticed ice starting to spread around her. Elsa quickly stood up and moved towards the window facing the North Mountain. For some reason the sight of it always seemed to calm her down. Once she regained her composure she reread that part of the book again and again. She wouldn't accept what it said. She couldn't. After hours of rereading the same paragraph she put the book down. She could feel tears rolling down her cheeks.

Quietly, barely loud enough for herself to hear it, she said, "I'm…adopted?"
